TROLLEY MECHANISM.

SPECFIOATION forming part of Letters Patent No.' 557,827, dated April'7, 1896.

Application filed November 23,1895. Serial No. 569,913. (No model.)

To all whom, it may concern: e

Be it known that l, JAMES KENNEDY, residing at IIollidaysburg, in thecounty of Blair and State of Pennsylvania, have invented certain new anduseful Improvements in rl`rolley Mechanism, of which the following is aspecification.

My invention relates to an improved trolley mechanism for electrically-propelled cars; and such invention has for its ob ject to provide atrolley and adjusting devices therefor of a simple and inexpensivenature which can be easily manipulated and which will effectively servefor their intended purposes.

My invention also has for its object to proprovide a trolley havingadjusting means operated from the interior of the car, and so arrangedthat the condition of the trolley can be observed both night and dayfrom the interior of the car.

vWith other minor objects in view, which will hereinafter appear, myinvention consists in such peculiar combination, and novel arrangementof parts as will be rst described in detail and then be speciiicallypointed out in the appended claims, reference being had to theaccompanying drawings, in which- Figure l is a view of the street-carwith my improved trolley mechanism applied; and Fig. 2 is a longitudinalsection of the car-top, showing my improved trolley mechanism in anoperative position.

In its practical arrangement my improved trolley mechanism is locatedcentrally of the car-body and is adapted to be operated from theinterior of the car, lookouts being provided in the top of the carthrough which the position of the trolley can be observed.

My improved mechanism comprises a hub or bearing-plate A, which isbolted to the top of the car centrally thereof and is centrallyapertured at B to receive the tubular stem of the trolley-carrying arms,suoli stem (indicated by C in the drawings) forming a rotary axis forthe trolley-arm, as most clearly shown in Fig. 2. To the stem O isiixedly held a bearing-plate D, to which, between the bifurcated end(Lis pivotally secured the lower end of the trolley-arm proper,E, thesaid lower end being curved inward, as at e, so as to admit of the saidarm being inclined when in engagement with the wire at an angle such asto bring the trolley in the line of sight as viewed from the lookouts Fin the car-top, such curvature of the trolley-arm also providing aconvenient attaching portion for a lantern G, having its bull-eye orlight-throwing face so arrange-d as to cast a light on thetrolley-wheel, such light device being provided to enable the conductoror motorman to see the position of the trolley-wheel at night when thetrolley slips the wire.

By referring to Fig. 2 it will be noticed the stem G carries at thelower end an inverted yoke-like member H, which is made fast to the saidstem bya set-screw I. The member H, it will be noticed, has at one end acurved portion h, having a slot t', in which is fitted an adjustablestop j, which maybe in the nature of a set-screw, as shown, the purposeof which is to form a stopv for the trolley-adjusting lever J, which ispivoted to the member 7o of the yoke H and has its handle portion Kprojected beyond the curved end 71 as shown.

L indicates an S-sha-ped iiat spring, the lower portion l of which ismade much larger than the upper portion'and has its bottom membersecured to the plate D, while its upper member has aninwardly-projecting arm M, to which is secured the upper end of aflexible connection N, which passes down through the tubular stem C andconnects with the lever J. The upper portion of the spring L has itsmember O terminate in an eye ln, to which is pivotally connected thelink P, the upper end of which is pivotally connected to an aperturedbracket R on ,the lower face of the trolley-arm, as shown.

From the foregoing description,taken in connection with the accompanyingdrawings, it is thought that the operation and advantages of my improvedmechanism will be readily understood. It will be observed that byproviding the lookouts, arranged as shown, the condition of the trolleycan at all times be ascertained from the interior of the car;furthermore, by supporting the trolley-holding devices `in the mannershown the trolley can be quickly and positively adjusted from the sideof the car; furthermore, by providing a spring arrangement, as describedand shown, it is manifest that the link connec- ICO tion will allowr thetrolley-arm to have the necessary free-swing movement necessary toaccommodate its traveling freely over the irregular trolley-wire. Again,the siinpliiied arrangement of the trolley-spring, While providing allthe spring-power necessary for the trolley-arm, allows Jfor a quick andeasy inanipulation of the lever J when it it desired to adjust thetrolley-arm.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is-

l. In a trolley mechanism, the combination With the turn-plate having atubular stein projected into the ear, a eoinpressible spring secured tothe turn-plate the trolley-arm pivotally secured to said plate, a linkconnection connected to the spring and the trolley-arm, and a pulldevice connected to the upper part of the spring projected through thetubular stem into the ear, all arranged substantially as shown anddescribed.

2. As an improvement in trolley mechanisms, the combination With theturn-plate and the stem D, C, the yoke member H, and trolley-arm J,pivotaliy secured to the plate D, at one side, of the spring L, securedat the lower end to the plate D, the linl; member P, and the iexibleconnection N, all arranged substantially as shown and for the purposededescribed.

8. The combination with the car having lookouts in the top, of aturn-table in the cartop centrally of the lookouts, said table having anoperatingdever disposed Within the ear, the trolley-arm having aninwardly-curved lneinber pivoted to the turn-table, a lantern held onsuch curved end With its light-throwing face directed toward thetrolley, the spring L, connected to the turn-table, the link-arm P,connecting the trolley-arm and the spring, and the pull-rod N, passeddown into the ear an d connected with the operating-lever, all arrangedsubstantially as shown and described.
